Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510464, here are decompositions:

5 + 31510459 = 31510464
17 + 31510447 = 31510464
31 + 31510433 = 31510464
61 + 31510403 = 31510464
67 + 31510397 = 31510464
101 + 31510363 = 31510464
241 + 31510223 = 31510464
277 + 31510187 = 31510464

Showing the first eight; more decompositions exist.
